The ancient Greek philosopher Epicurus posited happiness as life’s ultimate goal. But he also believed that our human fears often stop us from reaching that goal, and that only in freeing the mind from anxiety and worry can we experience freedom and peace. In fact, the lifestyle we now call “Epicurean” refers to one that focuses on the most basic joys of life: things like friendship, knowledge, virtue, and sense-based comforts such as food and good health. When we simplify life in that way, we can be at peace not only with ourselves but also with the people around us. Across millennia, Epicurus reminds us that the simplest pleasures, enjoyed in good company, are often the best.
